Deployment & Node Operations

This guide provides the technical specifications and procedural steps required to deploy a Sovereign Node within the Aegis-Graph network. Institutional nodes act as trusted validators, contributing to the global consensus of the Sovereign Academic Graph (SAG).

🏛️ Deployment Architectures

Mode	Use Case	Requirements
Edge Node	High-speed local auditing for single institutions.	Low latency, ARM64 optimized.
Consensus Node	Global validation and graph synchronization.	High availability, ECC RAM.
Archive Node	Full historical ledger of academic metadata.	High storage, NVMe RAID.

1. Prerequisites

💻 Hardware Specifications

• CPU: 8+ Cores (ARM64/Graviton recommended for efficiency).
• RAM: 32GB+ ECC DDR4/DDR5.
• Network: 1Gbps symmetrical uplink with static IP.
• Storage: 500GB+ NVMe SSD (Gen4 recommended).

🐧 Software Environment

• OS: Ubuntu 22.04 LTS or Amazon Linux 2023.
• Runtime: Python 3.11+, Docker 24.0.0+.
• Security: OpenSSL 3.0+, Fail2Ban, UFW/Firewall rules.

2. Fast-Track Installation

Deploy a standard Sovereign Node using our automated kernel bootstrap script:

# Initialize the Aegis-Kernel Environment
curl -sSL https://get.aclas.college/aegis-kernel | bash

# Configure your Institutional Identity
# Replace SOV_XXX with your assigned Institutional ID
aegis config --node-id SOV_ATL_0782 --api-key <YOUR_TOKEN>

# Launch the Multi-Agent Swarm
aegis start --mode consensus --workers 4

---

3. Containerized Deployment (Docker)

For high-availability clusters, we recommend using our official Docker images:

version: '3.8'
services:
  aegis-node:
    image: ghcr.io/aclascollege/aegis-node:latest
    environment:
      - NODE_ID=SOV_ATL_0782
      - PRIVACY_LEVEL=MAX (ZKE)
      - GRAPH_SYNC=TRUE
    volumes:
      - ./data:/var/lib/aegis/graph
    ports:
      - "8080:8080"
    restart: always

🔒 Security & Compliance

ZKE Privacy Protocol

All nodes must operate under the ACLAS Zero-Knowledge Evidence (ZKE) protocol. This ensures that:

1. No PII Storage: Personal data is processed in-memory and immediately scrubbed.
2. Metadata Hashing: Only cryptographic hashes of audit trails are synced to the global ledger.
3. Encrypted Handshakes: All MARS agent communications are TLS 1.3 encrypted.

---

🛠️ Troubleshooting

• Sync Latency: Check peer-to-peer connectivity using aegis status --peers.
• Memory Pressure: Ensure swap is disabled for maximum audit performance.
• Agent Failures: Review logs in /var/log/aegis/mars.log.
